POISON DUSTER.

Application mea october 3, 1924. Y serial No. 741,366.

To all whom t may concern.' L

Be it known that I, ALBERTy B. VEVER,

a citizen of the United States, residing at Chipley, in the county ofWashington and State of Florida, have invented certain new and usefulImprovements in Poison Dusters; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which itv ap'pertains to make and use thesame.

My invention relates to improvements in devices for sprinkling powders,and the present device is intended primarily for sprinkling or rdustingpowdered poisons over numerous kinds of growing plants, to preventattacking thereof by insects.

The object of the invention is toprovide an extremely simple andinexpensive device, yet one'which will be highly efficient and cannotclog.

With the foregoing in view, lthe invention i resides inthe novel subjectmatter hereinafter described and claimed, the description beingsupplen'iented by the accompanying drawing.

Figure l is a vertical sectional view of a powder cluster constructed inaccordance with my invention. d

Figure 2 is a horizontal sectional view on line 2 2 of Fig. l.

In the drawing above briefly described, the numeral l designates areceptacle which may well be in the form of a glass jar. A carryinghandle 2 is preferably provided for the receptacle l and it may well besecured to a collar 3 surrounding said receptacle, and the latter may beprovided with any preferred means, such as the ribs a, forholding thecollar against sliding thereon. The receptacle is provided withadischarge neck or mouth 5 with which a metallic cap G is engaged, thecap being preferably threaded upon the neck. This cap is provided with apowderfdischarge opening 7, and the outer edge of anannularscreen-carrying rim or wall 8, contacts with the inner side of said caparound said open- The outer edge of this wall 8 is provided with anexternal bead 9, and a ring 10, preferably formed of rubber, surroundssaid wall between said bead and the outer end of the neck 5,7said ringl0 serving to hold the wall 8V against movement into the receptacle,while the cap 6 holds it against outward movement.

i i In the construction shown, the innerredge Aof the wall 8 is formed`withaninterna-l bead VIl. A woven wire screen l2 is disposedV withinthis wall and contacts with the bead 11. A spacing ring 13 is positionedwithin the wall in contact with the screen 12 to hold the latter againstthe bead ll, and a second screen 14` within the wall 8, is held againstthe rspacing ring, by vcontact with the cap r6. Preferably, a thirdscreen l5 of 'concavo-convex form, is secured at its edge to the beadll, and in the spaces between the several screens, I place weights 16formed of any suitable material, so that when the entire device isshaken, these weights will strike the screens, thereby vibrating thelatter andy insuring that the powder inthe receptacle shall properlydischarge, without any danger of clogging the screens. f

Excellent results may be obtained from the details disclosed and theyalso produce an exceptionally simple and inexpensive construction. Thesedetails are preferablv followed, but within the scope of the inveritionas claimed, modifications may of course be made. i
